These markers indicates the current break condition. « I » means an instruction
break is active, « D » means a data break is active and « T » means a trace break is
active.
This symbol indicates when the emulator is executing an application program (RUN)
or is stopped (STOP).
When the Emulator has suspended its execution, the value of the current PC is
shown in red. The user can select the current PC (Program Counter) thanks to the
Option button and modify the value of the PC directly in the text box. The PC’s can
take value from 0 to FFF
When the Emulator has suspended its execution, the current value of the Accu is
shown. The user can modify the value of the Accumulator. The accumulator can
take value from 0 to F.
When the Emulator has suspended its execution, the user can modify the state of
the Z, Cy and Cy_int flags.
When the Emulator has suspended its execution, the user can modify the value of
the index registers. The index can take value from 0 to 7F. The two index registers
are automatically updated from the values entered
D Data Break Condition
T Trace Break Condition
